How can You Update Sony Drivers?

There are numerous of common alerts and also other messages which you might get in the driver updating process, many of which I've paraphrased and listed here together with information on what to do:

Windows can't verify the publisher of this driver software: If you received it directly from the manufacturer or from their installation disc, choose Yes to continue installing this driver only. Choose No if you downloaded the driver elsewhere and didn't exhaust your search for a manufacturer-provided one.

How to Update Drivers with Device Manager?

1. Open Control Panel

Depending on your version of Windows, Control Panel is usually available from the Start Menu or the Apps screen.

Note: If you don't see these options, your Control Panel view may be set to Large icons, Small icons, or Classic View, depending on your version of Windows. If so, find and choose Device Manager from the big collection of icons you see and then skip to Step 3 below.

2. Open Device Manager

From the open Control Panel window, click System, choose the Hardware tab, and then click the Device Manager button.

3. In Device Manager, you can check for updates, update your drivers or troubleshoot driver problems

2. Scan your PC for outdated drivers. Select the ones(here you should choose SONY VGC-RB51MV) you want to update and click download

3. After the download process is finished, you should click SETUP to install them. That's it! Your driver for SONY VGC-RB51MV has been updated. Sometimes a restart is required to let the drivers take effect.
